Beta 2015 upd 2 Dll problem with "libmmds.lib" linkage

Hello,

Beta 2016 update 2 has a problem with VS 2015 new run-time libraries. Consider the following code (should be compiled and linked as Win32/64 Dll):

#include <Windows.h>
#include <stdio.h>
#include <stdlib.h>
#include <mathimf.h>

#pragma comment( lib, "libmmds" )

//  Uncomment this to remove some errors
//  #pragma comment( lib, "legacy_stdio_definitions" )

BOOL APIENTRY DllMain( HMODULE hModule,
  DWORD  ul_reason_for_call,
  LPVOID lpReserved
  )
  {
  switch( ul_reason_for_call ) {
	case DLL_PROCESS_ATTACH:
	case DLL_THREAD_ATTACH:
	case DLL_THREAD_DETACH:
	case DLL_PROCESS_DETACH:
	  break;
	}
  return TRUE;
  }


__declspec(dllexport) void CalculateSomeStuff( double x, double& Val )
  {
  Val = pow( x, 2.3 );
}

If the target is 32 bit, then the linkage stage will give the errors:

ipo: : warning #11021: unresolved __snprintf
1>          Referenced in libmmds.lib(libm_error.obj)
1>ipo: : warning #11021: unresolved __vsnprintf
1>          Referenced in MSVCRT.lib(vsnprintf.obj)
1>ipo: : error #11023: Not all components required for linking are present on command line

If legacy_stdio_definitions is included, 32bit target will build successfully.

If the target is 64 bit, then the linkage step will give the errors:

1>  Win32Project1.cpp
1>ipo: : warning #11021: unresolved __imp__snprintf
1>          Referenced in libmmds.lib(libm_error.obj)
1>ipo: : warning #11021: unresolved __imp___iob_func

1>c:\vs_test\ConsoleApplication1\x64\Release\Win32Project1.dll : fatal error LNK1120: 4 unresolved externals

Including legacy_stdio_definitions will not fix the problem completely:

1>ipo: : warning #11021: unresolved __imp___iob_func
1>          Referenced in libmmds.lib(libm_error.obj)
1>ipo: : error #11023: Not all components required for linking are present on command line
1>     Creating library c:\vs_test\ConsoleApplication1\x64\Release\Win32Project1.lib and object c:\vs_test\ConsoleApplication1\x64\Release\Win32Project1.exp
1>libmmds.lib(libm_error.obj) : error LNK2019: unresolved external symbol __imp___iob_func referenced in function write_message

I believe the version of libmmds.lib should be somehow adjusted to new VS2015 run-time.
